Attentive.ai, the San Francisco-based AI construction software startup, secured $30.5 million in a Series B funding round led by Insight Partners in November 2025.
This round brings the company’s total fundraising to $48 million, with participation from Vertex Ventures, Tenacity Ventures, and InfoEdge Venture Fund.
What Is Attentive.ai and Its Vision?
Founded to tackle one of construction's most labor-intensive tasks, Attentive.ai developed Beam AI, a platform automating construction takeoffs—the measurement and quantification of project materials.
Used by over 1,200 contractors and suppliers, Beam AI delivers fully automated, AI-driven takeoffs with a human-in-the-loop validation model, drastically reducing manual labor hours and turnaround times.
The company’s vision is to build the most trusted preconstruction platform, extending beyond takeoffs into AI-supported estimating, bidding, and collaboration workflows.
CEO Shiva Dhawan emphasizes the company’s mission to power a decade of growth in construction by streamlining preconstruction processes that have remained largely manual.
